The following list of medications are in some way related to or used in the treatment of this condition.
How can acute diarrhea be managed?
- Drink liquids as directed. Liquids will help prevent dehydration caused by diarrhea. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you. You may need to drink an oral rehydration solution (ORS). An ORS has the right amounts of water, salts, and sugar you need to replace body fluids. You can buy an ORS at most grocery stores and pharmacies.
- Eat foods that are easy to digest. Examples include rice, lentils, cereal, bananas, potatoes, and bread. It also includes some fruits (bananas, melon), well-cooked vegetables, and lean meats. Do not eat foods high in fiber, fat, or sugar. Also, do not drink alcohol until your diarrhea is gone.
How can acute diarrhea be prevented?
- Wash your hands often. Use soap and water. Wash your hands before you eat or prepare food. Also wash your hands after you use the bathroom. Use an alcohol-based hand gel when soap and water are not available.
- Keep bathroom surfaces clean. This helps prevent the spread of germs that cause acute diarrhea.
- Wash fruits and vegetables well before you eat them. This can help remove germs that cause diarrhea. If possible, remove the skin from fruits and vegetables, or cook them well before you eat them.
- Cook meat and poultry as directed. Meat includes beef and pork. Poultry includes chicken, turkey, and duck.
- Cook ground meat to 160°F.
- Cook ground poultry, whole poultry, or cuts of poultry to at least 165°F. Remove the poultry from heat. Let it stand for 3 minutes before you eat it.
- Cook whole cuts of meat other than poultry to at least 145°F. Remove the meat from heat. Let it stand for 3 minutes before you eat it.
- Wash dishes that have touched raw meat or poultry with hot water and soap. This includes cutting boards, utensils, dishes, and serving containers.
- Place raw or cooked meat in the refrigerator as soon as possible. Bacteria can grow in meat that is left at room temperature too long.
- Do not eat raw or undercooked oysters, clams, or mussels. These foods may be contaminated and cause infection.
- Drink only filtered or treated water when you travel. Do not put ice in your drinks. Drink bottled water whenever possible.
